D) nucleoprotein
E) pili protein

Question

Quizplus · Accepted Answer

The enzyme that allows the reforming of a circular plasmid following conjugation is called relaxase. Relaxase is an enzyme that is responsible for nicking the circular plasmid DNA, allowing for one strand to be transferred to the recipient cell while the other strand remains in the donor cell. It is then able to reseal or ligate the nick, restoring the circular plasmid in both cells. The relaxosome is a complex of several proteins and DNA sequences that facilitate the transfer of the plasmid during conjugation. The F' factor is a type of plasmid that carries genetic information for mating and conjugation, and pili protein aids in the attachment of the donor and recipient cells. Nucleoprotein refers to any protein that interacts with DNA or RNA.
